TEMPERATURE MAP CREATION

A method is provided of creating a 3D temperature map of a component. The method includes the steps of: (a) providing plural shape models of the component corresponding to respective camera views of a 3D CAD model of the component; (b) providing plural images of the component captured after a therma...

More Information
Summary:A method is provided of creating a 3D temperature map of a component. The method includes the steps of: (a) providing plural shape models of the component corresponding to respective camera views of a 3D CAD model of the component; (b) providing plural images of the component captured after a thermal paint test, each image being a view of the component corresponding to a respective one of the shape models; (c) extracting data from each image by performing the sub-steps of: (c-i) adjusting the position and/or orientation of each shape model so that the camera view of the CAD model provided by that shape model matches the view of the component provided by the corresponding image, and (c-ii) identifying temperature bands within the images and encoding the temperature bands within the matched, corresponding shape models; and (d) forming a 3D temperature map of the component from the encoded temperature bands.
